N a nonreturn valve in a pump suction to prevent the pump draining or depriming when not in service 抽水泵 (Also called foot valve)
Press the "Start" button, the pump running, then open the suction valve of the pump.
按下水泵“开”按钮，泵即运转；然后打开泵的吸入阀。
How it works: the piston moves from left to right, form a negative pressure pump cylinder, then the suction tank fluid through the valve into the pump cylinder.
工作原理：活塞自左向右移动时，泵缸内形成负压，则贮槽内液体经吸入阀进入泵缸内。
Project standard STPE-0101 page 43 requires that the suction piping up to suction block valve (including the valve) should be rated as discharge piping.
